Development and validation of a nomogram for predicting antibiotic treatment duration in patients with liver abscess complicated by diabetes.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study aimed to identify the recovery predictors for patients with pyogenic liver abscess (PLA) and diabetes who are undergoing antibiotic therapy, and to develop an effective nomogram for predicting the antibiotic treatment duration (ORT). This retrospective study included consecutive PLA patients with diabetes who received antibiotic treatment, with ORT defined as the time from the initiation of antibiotic therapy to its cessation. Univariate and multivariate analyses were performed to identify the main predictors of ORT. Kaplan-Meier survival curves and a nomogram were subsequently constructed to predict ORT, and the accuracy of the nomogram was assessed using Harrell's C-statistic and calibration curves. A total of 139 PLA patients with diabetes were included, with a median ORT of 17 days (interquartile range: 13-22 days). The study found that fever (P < 0.01), pre-treatment septic shock (P < 0.01), abscess diameter greater than 5 cm (P < 0.01), and elevated white blood cell count (P = 0.04) were independent risk factors for prolonged ORT, suggesting that patients with these factors had a significantly longer ORT compared to those without them. Prognostic analysis showed that patients exhibiting more predictive factors (e.g., high fever, shock, larger abscess, elevated white blood cell count) had a significantly extended ORT. Based on these factors, we developed a nomogram to predict ORT, with a Harrell's C-statistic of 0.75, indicating good predictive accuracy. The calibration curve for predicting ORT demonstrated good consistency between the expected and actual results. This nomogram provides clinicians with a simple and practical tool to assess patient prognosis and guide the appropriate cessation of antibiotic treatment.
